pretty good idea foreal

yo if you wanna to perfrom an easy method to get premier balls (if you prefer them better) you should definetly sell all your poke balls and thenm buy 10 then sell 10 and each time you get 1 free its ill

It sounds good and all, but when you sell Pokéballs it's only worth half that you you buy it. So you end up paying quite a lot for each premier ball. They aren't any better than Pokéballs anyway, so just buy 10 Pokéballs at a time
